, -IMPROVED ROADSCRAPER.

The Schedule referred to in theseLeti-.ers Patent and part of the eamo.

To all whom 'it 'ma/y conce/rn:

Be it known that I, WILLIAM W. RUMRILL, of Roanoke, in the county ofHuntington, and State of Indiana, have invented a new and improved Road-Scraper; andI do hereby declare that the following is a full, clear, andexact description thereof, Whichwill enable others skilled in the art tomake and use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure lis acentralsection of my improved roadscraper,through the linea x, fig. 2.

Figure 2 is a plan View ofthe same.

Similar letters of reference indicate corresponding parts,

This inventionrelates to an improvement in revolving road-Scrapers andIt consists in the combination of parts 'as will be hereinafter morefully described.

d are the pintles on which the scraper revolves. These pintles passthrough the handle-boards B B', and their projecting ends, entering inholes in the'board A, afford axial points on which the scraper revolves.

The outer ends of these pintles terminate in eyes, in which thedraught-bail e is hooked.

'The handle-boards are connected rigidly, by meansA of a stoutcross-piece, O, which is recessed' to afford.

space rfor the operation of the catches f and h.

The catch h is a Hat piece of wood or metal, having its front edgebevelled upward, so that the back edge of the scraper will enconnterit,and push it backward against the tension of the spring t, in rear of the2 catch., which spring keeps the catch protruded, after the edge ofthescraper has passed upward.

The catch fis a similar flat piece of wood o r plate of metal, which ispivoted centrally tothe 'top board k, which latter vibrates on a pivot,j, its opposite end being guided by a guide-rod, or arm, l, affixed tothe handle, as shown. v

The catch f is also4 actuated by its spring 13, as shown. 1 The twocatches hold the scraper in the proper positiou with respect to thehandles, when the apparatus is being used, and when the front scoop ofthe scraper is lled, the operator raises the handles B', and, at theSametime, draws the rod m, which leads from the free-- end of the boardk.'

This movement draws back the catch f, leaving the scraper `free to turnover forward, discharging its contents `and passing the catch h, whichis thrown back automatically, and again protruded, to hold the scraperin line with the handle-board.

I am aware that revolving scrapers have been made, and desire `to beunderstood as not claiming, broadly, a revolving scraper, having catchesand other accessory devices; but having thus described my invention,

What I claim as new, land desire to secure by Letters Patent, is`

The combination' of the catches j' h,- springs t, pivoted top board Ic,guide-iron L, and operating-rod fm, with the boardsB B', cross-piece C,and the revolving scraper, all arrranged as herein described, for thepurpose specified.
